CHARLES W. GLIDDEN, OF LYNN, MASSACHUSETTS.

HEEL-SLICING MACHINE.

SPECIFICATION forming part of Letters Patent No. 224,011, dated February 3, 1880. Application filed November 18, 1879.

To all whom it may concern Be it known that I, CHARLES W. GLIDDEN, of Lynn, county of Essex, State of Massachusetts, have invented an Improvement in Heel- Slicing Machines, of which the following description, in connection with the accompany ing drawings, is a specification. 1

This invention relates to mechanism for slicing aheel-pile or a so-called heel-sausage, such as described in another application filed by me concurrently with this, into hecllifts of any desired thickness.

In this my invention the heel-pile to be antomatically out, it being composed of pieces of leather, preferably of heel shape, pasted and consolidated or compacted closely together, and of suitable length, is placed upon a suitable guideway between feeding devices, herein shown as reciprocating clamps, which are movedforward and backward from the cutter.

The cutter has a drawing or shaving cut, an d during its operation the heel-lift being cut from the pile is operated upon by a presser, which, besides holding the lift in proper position, also enables the knife to enter the pile directly and withoutliability of being deflected from its true course.

The forward end of the heel-pile is by the feeding devices always thrust forward snugly against the presser, which acts as a gage, and during the cuttingoperation the presser provided with rollers is drawn across the end of the heel-pile substantially in-line with the acting-edge of the cutter.

Figure ,1 represents a front-side view of a heel-pile-slicin g machine provided with "my improvements; Fig. 2, a top View thereof 5 Fig. 3, aview of the back end of the machine; Fig. 4, a view of the front end; Fig. 5, a section on the line 00 a, Fig. 2; and Fig. 6 isa detail of the cutting devices.

The principal working parts of the machine are mounted upon a post, at, having attached to it a strong and very stiff yoke, 12, to sustain the strain of the cutting devices, to be hereinafter referred to. i

The main'shaft c of the machine, held in bearings cd, has a toothed gear, 6, in engage.- ment with and driven by a pinion, f, on the shaft 9, which is driven in any usual way by a belt on the fast pulley of the pair of pulleys h i.

The shaft 0 has upon it a camgrooved hub, j, and a cam-grooved disk, 70. The groove in' hub j receives a pin or roll on the feed-slidemoving lever I, mounted on an adjustable fulcrum-block, 4%, held in a slot in an ear, m, of the bracket 0, the said lever being slotted at its side, asat 3, Fig. 3, to receive the set-screw 4, which holds the lever in position with relation to the block a, fitted loosely on its holding-stud 5.

The forward end of lever l, slotted, as shown in dotted lines, Fig. 2, is made to embrace a loose square block, 7, on a pin, 8, depending from and so as to reciprocate the feed-actuating slide q, fitted in wideways 1'. By adj usting the fulcrum-block the throw of the lever lis adjusted so as to vary the length of feed of the heelpile.

The slide g has logs or lips q, to embrace blocks 8, slotted diagonally, as at 10, to receive the pins 12 of the pivoted feedingjaws13, having teeth 14 to engage the heel-pile, the pivot u of the said jaws being connected with slides 15, held and adapted to slide longitudinally between suitable guides 16. The heelpile, several inches (orit may be feet) in length,

slide is withdrawn the jaws are opened and drawn back along over the heel-pile.

The slides 15, which carry the jaws, are held in boxes 0. 11 under the control of a right and left threaded screw, 0 having a thumb-nut,0l by turninggvhich the guideway to may be made of proper width, and the jaws be fitted to grasp heel-piles of any desired size.

The heelpile is kept down in the guideway w by the adjustable holder 6', forked to fit the circular or most curved part of the heel-pile, and controlled by an adjusting-screw, 9

The grooved cam-disk 7c actuates the lever h attached by the adjustable link 0?, through a ball-and-socket connection, j with alever, k pivoted at Z on an adjustable bracket, m held to the frame-work by a set-screw, M, in a slot in the said bracket. The outer end of the said lever 70 is slotted, and receives a square block, on a pin of the slide 12 held in or under suitable guides g the said slide at top carrying the presser or, having rollers 18, which act upon the leading end of the heelpile when it is fed forward, to serve as a stop and gage for the end of the heel-pile.

The lever k reciprocates the presser, causing it to rise into position before thefeed-jaws move forward, and causing it to descend diagonally across the end of the heel-pile from which the lift is to be cut as the knife or cutter 1, carried by the reciprocating head 8 and having its cutting-edge placed diagonally to its line of reciprocation, as shown in Fig. 3 aud'in dotted lines in Fig. 4, is moved forward, and its edge consequently downward, to sever a heel-lift from the heel-pile.

The cutter-carrying slide 8 is shaped to embrace the upper and lower edges of a guidebar, t supported on brackets 10 of a plate, 00 and is actuated by the slotted lever a set in motion by the crank-pin (L3 on the toothed Wheel 6, before described.

By thismaehine the heel-pile may be automatically cut into heel-lifts of an y desired thickness, and the lifts so'cut will be uniform throughout.

Instead of feeding-jaws, it is obvious, I might employ intermittinglyoperated feedingwheels, such as are common in sewing-machines. 7

By adjusting the bracket m the presser may be removed more or less distant from the path of the cutter, according to the thickness of the heel-lift to be cut off. i

The pressure of the presser against the end of the heel-pile being cut is, in practice, very :onsiderable, and to reduce the work of the ever k in moving it I have added to the )I'GSSGI a roller, 0, which is acted upon by an nclined part, 01 of the under side of the slide which is parallel with the edge of the cuter 4.

I claim- 1. In a heel-slicing machine, the combination of the intermittingly-operating feeding mechanism to feed the h eel-pile forward, a presser to serve as a stop for the forward end of the heelpile, and acuttingblade, the combination being and operating substantially as described.

2. The feeding-jaws and guideway 10, combined with the adjusting-screw,substantially as and for the purpose described.

3. The feedin g-jaws, combined with the feeding-slide and the slotted blocks, to close and move the jaws forward, substantially as described.

4. The feeding-j aws and feeding-slide q, combined with the lever 1, having the movable fulcrum, substantially as and for the purpose described.

5. The forward and downward moving outter, combined with the presser provided with rollers to act upon the end of the heel-pile, and adapted to be moved diagonally across the said end as the cutter severs a heellift from the pile, substantiallyas and for the purpose de-' scribed.

6. The'reciprocatory cutter, combined with the presser madelon gitudinally adjustable with relation to the cutter to insure the production of heel-lifts of the proper or any desired thickness, substantially as set forth.

7. The combination, with the adjustable guideway to receive the heel-pile, of the adjustable holder 0 to operate upon the most curved part of the heel-pile, substantially as described.

8. The horizontally-movable cutter-carryin g slide 8 and the cutter T with its cutting-edge placed diagonally with relation thereto, combined with a guide, upon which the said slide moves.

9. The presser provided with the roller or stud a, combined with the slide 8 provided with the incline (1 substantially parallel with the cutting-edge of the cutter r substantially as and for the purpose described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

. CHARLES \V. GLIDDEN.
